Paper Abstract

In view of the infrared athermalization design initial system difficult to make the selection, material requirements, introduced infrared material selection and sorting system, from the input parameters, to determine the initial system, this paper has fully modular programming. In this paper, the telephoto system combined with poor heat dissipation model, analyzed a perturbation type far infrared wavelengths passive design method of athermalizing lens. Deduces the relationship between the focal power allocation between them, and to unify the two directly by heat dissipation taken away and the difference between objective lens focal power allocation relation. Cut the infrared system selection process, radically reduce the infrared optical system design cycle. In order to verify the feasibility of this method, designed a long shots than 0.8, the range of temperature compensation for - 45 ° ~ 60 ° infrared wavelengths of athermalization telephoto lens.
